Problems solved by technology

[0004] However, in the testing technology solutions provided by the existing technology, the workload of scripting related test cases is very large, and manual construction of repetitive and cumbersome interface test cases is required, as well as manual editing of functions suitable for different simulation platforms. Test cases consume a lot of time, which reduces the efficiency of test execution and prolongs the development time of ECU

Abstract

The invention discloses an ECU automatic test method and system, a storage medium and a device, and the method comprises the steps: obtaining test information in an ECU test demand when the ECU test demand is received; wherein the test information at least comprises a test item, a test stage and a test platform; generating a corresponding interface test case according to the test information and apreset signal corresponding table; generating a corresponding function test case according to the test information, a preset function specification and a preset format specification; selecting a corresponding simulation platform and a corresponding test function according to the test information; and based on the simulation platform, automatically testing the interface test case and the functiontest case according to the test function. By adopting the technical scheme, the time for manually generating the test case can be saved, the test execution efficiency is improved, and the developmenttime of the ECU is shortened.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an ECU automatic testing method, system, computer-readable storage medium and device. Background technique [0002] ECU (Electronic Control Unit) electronic control unit, also known as "driving computer", "vehicle computer", etc., is a microcomputer controller for automobiles in terms of use, and is also called a single-chip microcomputer for automobiles. It is the same as ordinary single-chip microcomputers. It is composed of large-scale integrated circuits such as processor (CPU), memory (ROM, RAM), input / output interface (I / O), analog-to-digital converter (A / D), and shaping and driving. [0003] The automotive electronic control system includes three parts: sensor, ECU and actuator. The sensor is the interface for the ECU to collect various information of the car (such as vehicle speed, engine speed, cooling water temperature, intake pressure, ignition switch, etc.). Analyze...
